Jeep 55116884AA Fan Cooling Mechanical

If the electric cooling fan does not work, check the fuses and test the fan motor. The mechanical cooling fan on the 3.7L and 4.0L V6 engines with the heavy-duty cooling package should be checked for excessive bearing play and fluid leakage. It should turn willingly when the engine is cold and have more drag when the engine is warm. To replace the fan, disconnect the battery, use a special spanner wrench if necessary, and lower the fan and clutch assembly into the fan shroud. Disconnect the electrical connector, remove the shroud mounting bolts, and raise the fan and shroud assembly out the engine compartment. Finally, install the fan and clutch assembly securely.
